More than 800 people died of suspected mpox across the continent in that time, the U.N. health body said in its report. Congo's central African neighbour Burundi has also been hit by a growing outbreak, it added.
Mpox can spread through close contact. Usually mild, it is fatal in rare cases. It typically causes flu-like symptoms and pus-filled lesions on the body.
The WHO statement did not give comparative figures from previous years. The African Union's public health agency has said 14,957 cases and 739 deaths were reported from seven affected states in 2023 - a 78.5% increase in new cases from 2022.
